HEDRICK, TL; Univ. of Washington: Low-speed turning kinematics of the rose-breasted cockatoo Maneuvering flight is a crucial component of the natural behavior of the majority of bird species. This study couples 250 Hz 3D kinematics with bilateral electromyograms (EMGs) from eight flight muscles to examine the aerodynamic and neuromuscular mechanisms birds employ to initiate and […]

ALTSHULER, Douglas L.; DICKSON, William B.; DICKINSON, Michael H.; Caltech; Caltech; Caltech: Kinematics, aerodynamics, and increased wing-wake interactions in the hovering flight of honeybees, Apis mellifera. During hovering flight, an animal�s wing tip velocity is a function of its wing length (R), wingbeat frequency (f) and stroke amplitude (Φ). f is inversely correlated with R […]

IRIARTE-DIAZ, J.*; LEE, M.-M.; Brown University; Brown University: Kinematics of slow turning maneuvering in bats Maneuverability is an important feature for flying animals as they need make turns to capture prey or move around in their environment. The fundamental mechanism used to maneuver during flight is the asymmetrical generation of aerodynamic forces by the wings. […]

BISHOP, K.L.; Brown University: Kinematics of short glides in the Southern Flying Squirrel, Glaucomys volans Gliding flight is of special interest to those who study animal locomotion both because it is a possible precursor to powered flight and because it appears to be an energetically cheap mode of transport. Before we can meaningfully address questions […]

WARRICK, Douglas R.; TOBALSKE, Bret W.; POWERS, Don R.; Oregon State University; University of Portland; George Fox University: Kinematic Symmetry and Aerodynamic Asymmetry in the Hovering Flight of Hummingbirds Hummingbirds sustain hovering using kinematics unique among birds. Because of the apparent symmetry of their upstroke and downstroke, it has long been assumed that during hovering […]

FRY, SN*; SAYAMAN, R; DICKINSON, MH; ETH/University of Z�rich; Bioengineering, CalTech; Bioengineering, CalTech: Instantaneous flight power in the fruit fly Drosophila Hovering fruit flies are required to generate sufficient flight power to overcome aerodynamic and inertial forces. The aerodynamic models developed by Ellington (1) provide the theoretical framework for estimating flight power based on time-averaged […]

DICKSON, WB; DICKINSON, MH; California Institute of Technology; California Institute of Technology: Insect flight simulation Many insects are capable of sustained controlled flight. A comprehensive understanding of the mechanisms underlying the control of insect flight requires a dynamic model of the system. In this study a dynamic flight simulation of the fruit fly Drosophila melanogaster […]

TOBALSKE, B.W.*; WARRICK, D.R.; POWERS, D.R.; Univ. of Portland; Oregon State Univ.; George Fox Univ.: Dynamics of the hummingbird wake during forward flight over a wide range of speeds. Hummingbirds fly with their wings almost fully extended during their entire wingbeat. This pattern is associated with having proportionally short humeral bones and long distal wing […]

RICE, A.*; BLUMENSHINE, S.; TSUKIMURA, B.; California State University, Fresno; California State University, Fresno; California State University, Fresno: The Influence of Environmental Parameters on the Invasive Chinese Mitten Crab, Eriocheir sinensis, Zoeae Recruitment Dynamics in San Francisco Bay, CA The Chinese mitten crab, Eriocheir sinensis (Crustacea: Decapoda: Grapsoidea), invaded San Francisco Bay, CA, in 1992. […]

ALLEN, Jonathan D*; MCALISTER, Justin S; Bowdoin College; University of North Carolina at Chapel Hill: Testing rates of planktonic versus benthic predation in the field Predation is thought to be the most important source of embryonic and larval mortality for benthic marine invertebrates. However, few estimates of larval mortality exist and more precise estimates of […]
